The hardest boss of tier 14?

So forum community,
Now that we've had a good long time to digest this content, what do you think is the single hardest encounter in tier 14?
Choose as many answers as you think were really tough, and reply with your hardest boss for normal and heroic mode!
For me its definitely:
Normal: Garalon, hes a major cockblock, we have the most wipes on him.
Heroic: Haven't done it, but heroic sha looks absurd, because focusing for 22 minutes.
What do you guys think?
Poll coming up soon, but since it only lets me have 15 options, let's leave stone guard off.

imperial vizier zorlok on hc is the most fucking hardest boss in the tier mostly due to ppl failing on atenuation in p2 >_>
on normal garalon

but really imo sha hc is easy as shit just booooooooooooooooooooooooooooooooooooooooring and repetitive, empress is the 3rd easist hc on hof the fight is a joke once ur tanks learn how to survive p2. and reset kings was just rng with the fixed order is a completly joke.

edit: also some ppl metion hc elite protectors after the nerf the fight is actually a joke u just need good gear and interrupt and extend p1 as long as u can to get to p3 with ppl at least 8stacks

Elite Protectors is much harder than Sha. Sha isn't even hard, it's just an incredibly long time consuming fight.

Not right now. Elite Protectors is basically "Do your melee have geared ranged alts?". It really isn't that hard as long as you have the roster to pull it off (3 melee + 15 ranged is the norm).

Sha is a pretty tight DPS check when you first get to it (platforms are tightly tuned) and you have to figure out a good balance of add dps to boss dps in p2. Boring, sure. Still harder than any other fight this tier.

When it comes to progression, I'd have to say Heroic Stone Guard has been the hardest fight so far. My group still spends quite a bit of time on that fight each week. On normal, I'd say Amber Shaper. We had to really drill it into our raiders' heads that they have to interrupt.

Let's set some things straight. Heroic Tsulong is, by far, the hardest fight this tier. The RNG of night phases and blowing CDs for when sunbeams blow up make for a terrible fight.

Heroic Elite Protectors is actually EASIER than normal heroic protectors.
Heroic Sha is a boring AOE fest with no real DPS check. (We 4 tanked it, completely eliminating the platform dps check) If you do not 2/3 shot this on farm, your strat is probably bad.
Heroic Empress was hard, but is now nerfed.
Heroic Amber Shaper is not a hard fight at all, if you have strong tanks. And the personal responsibility? Blow 2 or 3 raid cooldowns if someone you're not sure of gets Abom.
